rDMODd4b20dcdc279: Add new class ExtendedSWHID as an alternative to SWHID/QualifiedSWHID
Summary

Following the discussion on T3034, we decided to replace SWHID with
two or three classes:

  • QualifiedSWHID to replace the existing SWHID (standard types + qualifiers)
  • CoreSWHID, for "core SWHID" only (standard types + no qualifiers)
  • ExtendedSWHID for internal use in Software Heritage (extra types + no qualifiers)

This commit adds the last one.

It also removes "ori" as a valid object type for CoreSWHID and
QualifiedSWHID, as it now only belongs in ExtendedSWHID.

Depends on D5117.

    Use dict instead of temporary SWHID when parsing {Core,Qualified}SWHID.
    
    It is cleaner, avoids warnings, and will be needed when introducing
    ExtendedSWHID in a future commit.

    Add new class QualifiedSWHID to replace SWHID, and deprecate the latter.
    
    Following the discussion on T3034, we decided to replace SWHID with
    two or three classes:
    
    * QualifiedSWHID to replace the existing SWHID (standard types + qualifiers)
    * CoreSWHID, for "core SWHID" only (standard types + no qualifiers)
    * ExtendedSWHID for internal use in Software Heritage (extra types + no qualifiers)
    
    Since migrating from SWHID will break existing code, this commit uses
    the opportunity to modernize it a little, ie.:
    
    * `keyword`-only constructor, to get rid of the hacky default values for
      `object_type` and `object_id`
    * enum instead of strings for the object type
    * `bytes` instead of an hex string for the object id
    * rename `metadata` to `qualifiers`

"RAW_EXTRINSIC_METADATA" is a horribly long mouthful.
(But I don't have better suggestions at the moment...)

I agree, but we don't have a better name; and that one is already used in various places

This looks fine.

Please consider adding a test that ExtendedObjectType is a superset of ObjectType?

I see you've extended the CoreSWHID parser test to check that it rejects the extended object types. Would it make sense to extend this test (and the ExtendedSWHID counterpart) to check *which* ValidationError triggered (in another diff)? It's probably just a matter of adding a substring of the ValidationError to the pytest.mark.parametrize args. (Maybe it's overkill? I don't know.)

swh/model/identifiers.py
64–66

Could we use the enum values instead of duplicating these vars?

717–735

These two dicts look like fairly easy candidates for deletion (in a further diff)?

swh/model/tests/test_identifiers.py
1513

This could probably be a pytest.mark.parametrized test instead of a for loop.

This revision is now accepted and ready to land.Feb 23 2021, 11:16 AM

Ah, I see you're doing that in D5121. Carry on.

Sure, done.

No, @zack doesn't want us to test error strings. We could add exception subclasses instead, but I don't see the point
